Jeep Wrangler MPG, gas tank, tires, and towing

JK and JL at a glance

• JK, 2008–2011: 3.8-liter V6 with a 6-speed manual or 4-speed automatic. Two-door and four-door Unlimited bodies.
• JK, 2012–2018: the 3.6-liter V6 replaced the 3.8, with a 6-speed manual or 5-speed automatic. For 2018 the JK was sold alongside the new JL as the Wrangler JK.
• JL, 2018 and later: 3.6-liter V6 (with an eTorque mild-hybrid version for 2020–2023) or a 2.0-liter turbo four-cylinder, mostly with an 8-speed automatic. The JL also brought a 3.0-liter EcoDiesel (2020–2023), the 4xe plug-in hybrid (from 2021), and the 6.4-liter 392 V8 (from 2021).

Wrangler gas mileage by year

Open a model year to see each EPA version. A Wrangler is tall, square, and geared for the trail, so it trails other SUVs on fuel economy. The JL improved on the JK by 2 to 3 mpg, and the EcoDiesel was the most efficient Wrangler at up to 25 mpg combined. The 4xe figure here is for gasoline only; it can also run on stored battery power for short trips.

EPA estimates for new vehicles from fueleconomy.gov (U.S. EPA and U.S. DOE), data retrieved November 12, 2026. Your mileage will vary with how and where you drive. EPA data on this site starts with the 2010 model year.

Gas tank size and range

The tank depends on the body: four-door Wranglers have the bigger one. The EcoDiesel has an 18.3-gallon tank and the 4xe a 17.2-gallon tank. Range below is the tank size times the EPA combined rating, a best case. Off-road crawling, big tires, and a roof rack all cut it. To cost out a trip, use the trip gas cost calculator.

Wrangler tire size and pressure

JL tire sizes depend on the trim: a Sport rides on 17-inch tires, a Sahara on 18-inch, and a Rubicon on LT285/70R17 off-road tires. The Xtreme 35 package and the 392 use 35-inch LT315/70R17 tires. Jeep’s manuals do not print one pressure; it is on the tire placard on the driver’s door frame. If you change to a different tire size, ask the tire shop for the right pressure for that tire and load. If the warning light comes on, see tire pressure light.

Wrangler oil at a glance

A JK takes 5W-20 and holds 6 quarts with the filter. A JL with the 3.6 V6 takes 0W-20 and holds 5 quarts; the 2.0 turbo takes full synthetic 5W-30, also 5 quarts. The 392 V8 needs 0W-40 and the EcoDiesel 5W-40. Every year and engine: Wrangler oil type and capacity.

Wrangler towing capacity

A Wrangler’s towing limit depends on the doors, the engine, and the axle ratio:

• JK, 2008–2018: 1,000 to 3,500 lb, depending on the body and the axle ratio.
• JL two-door: 2,000 lb. JL four-door, EcoDiesel, 4xe, and 392: 3,500 lb.
• 2024 and later four-door Rubicon with the automatic, LT285/70R17 tires, and the 4.10 axle: 5,000 lb.

Your exact rating is in the towing table of your manual or on jeep.com. Frequent towing also moves several items to the severe schedule: see the Wrangler maintenance schedule.

• JL generation (2018–2026): up to 5,000 lb¹⁶
• JK generation, 3.6L years (2012–2018): up to 3,500 lb⁵
• JK generation, 3.8L years (2008–2011): up to 3,500 lb²

Recalls: check by VIN

Recalls depend on the exact vehicle, not just the year. Enter your 17-character VIN at nhtsa.gov/recalls to see any open recalls on your Wrangler. The VIN is at the lower driver’s-side corner of the windshield and on your registration. A Jeep dealer does recall repairs for free.

What to record in your log

• Each fill-up: date, odometer, and gallons. Two full fill-ups in a row give your real MPG; the MPG calculator does the math. Note trail days and bigger tires, since both change the number.
• Each oil change: date and odometer. The oil change indicator forgets the last service when it is reset.
• Off-road trips, water crossings, and towing. They decide whether you follow the severe schedule for the axles, transfer case, and air filter.
• Tire size changes. Larger tires change speedometer and odometer readings unless the vehicle is recalibrated, which skews MPG math.

A car maintenance log keeps this in one place. More on Jeep’s service system: Jeep maintenance schedule.
